Advanced engineering systems serving chemical, electronic manufacturing, and clean energy sectors across Vietnam.
Vietnam has emerged as one of the most dynamic manufacturing hubs in Southeast Asia. The continuous expansion of key industrial zones in regions like Bac Ninh, Binh Duong, Dong Nai, and Hai Phong has drastically increased the demand for high-purity industrial gases. Industries such as electronics manufacturing, steel production, petrochemical processes, and food preservation rely on precise, reliable gas purification systems to maintain production quality and safety standards.
Under Vietnam's Power Development Plan VIII (PDP8), there is a strong shift towards cleaner energy alternatives, including LNG imports and green hydrogen technologies. This policy transition necessitates sophisticated Gas Purification Systems, particularly for natural gas dehydration, acid gas removal, and biogas upgrading, to meet strict carbon emission targets and supply high-quality energy to the national grid.
Did you know? Vietnam's commitment to achieving Net-Zero carbon emissions by 2050 is driving a massive industrial adoption of Carbon Capture, Utilization, and Storage (CCUS) and high-efficiency hydrogen production systems.
In the high-tech electronics factories of Bac Giang and Thai Nguyen, ultra-pure nitrogen (up to 99.999% purity) is critical to prevent oxidation during semiconductor fabrication. Our PSA and VPSA nitrogen generation and purification systems offer localized, cost-effective alternatives to liquid nitrogen delivery.
Furthermore, the agricultural powerhouse of the Mekong Delta is increasingly adopting biogas treatment technologies. Raw biogas contains high concentrations of H₂S and CO₂, which are highly corrosive. By implementing specialized biogas treatment engineering and CO₂ removal systems, local agricultural enterprises can refine crude biogas into clean biomethane, generating power and reducing environmental footprint.
For offshore gas fields in the Nam Con Son and Malay-Tho Chu basins, our custom-engineered natural gas surface production equipment and acid gas removal units are built to withstand harsh marine environments and deliver pipeline-ready dry gas.

Understanding the engineering behind high-efficiency air separation and gas purification processes.
Pressure Swing Adsorption (PSA) and Vacuum Pressure Swing Adsorption (VPSA) are highly reliable methods for generating high-purity nitrogen and oxygen directly on-site. For Vietnamese enterprises, this eliminates the logistical complexities and high costs associated with liquid gas transportation.
Our PSA systems utilize high-grade Carbon Molecular Sieves (CMS) to selectively adsorb oxygen molecules from compressed air, allowing high-purity nitrogen to pass through. For oxygen generation, Zeolite Molecular Sieves (ZMS) are employed to adsorb nitrogen. These systems are engineered with energy-saving valves and intelligent PLC controllers to minimize power consumption—a key consideration under Vietnam's rising industrial electricity tariffs.
For large-scale industrial operations, such as metallurgy plants and chemical complexes, Cryogenic Air Separation Units remain the gold standard. These systems cool air to liquefaction temperatures (below -180°C) and separate the components (nitrogen, oxygen, argon) based on their boiling points through fractional distillation. Huayan's cryogenic units are optimized for maximum thermodynamic efficiency, ensuring low operating costs for high-volume gas production.
As industrial plants in Vietnam align with environmental mandates, removing acid gases (such as hydrogen sulfide - H₂S and carbon dioxide - CO₂) from processing streams has become mandatory. Our wet process CO₂ removal systems utilize amine solvents or physical absorption methods to scrub carbon dioxide from process gases.
This technology is critical not only for natural gas processing but also for the emerging Carbon Capture, Utilization, and Storage (CCUS) sector, helping Vietnamese manufacturers lower their carbon tax liabilities and comply with international export standards like Europe's CBAM.
With the global push towards a hydrogen economy, green hydrogen is gaining significant traction in Vietnam. Our Alkaline Water Electrolysis Hydrogen Production Systems offer a clean method to produce high-purity hydrogen by splitting water molecules using renewable electricity. The resulting hydrogen gas is purified to meet the stringent requirements of fuel cells, chemical synthesis, and metallurgical reduction processes.
